The ADP2121 is the first of a family of high-frequency 6-MHz dc-to-dc regulators. The ADP2121 is available in a 1.3-mm - 0.9-mm wafer level chip scale package (WLCSP) with a razor-thin height of 0.6 mm. The device requires only two small capacitors and one small inductor, resulting in a 35-percent reduction in PCB area compared with current 3-MHz buck regulator solutions, according to ADI.

Pricing: $0.80 per unit in 1,000-unit quantities.
Availability: Samples are available now in a 6-ball WLCSP.
